Patented Mar. 1936 UNITED STATES PATENT OFFICE TRAVELER TYPE RING SPINNING MACHINE Application June 22, 1935, Serial No. 27,932

5 Claims. (01. 118--59) This invention relates to machines for spinning artificial silk and particularly to the traveler type of ring spinning machine.

One object of my invention is to provide an improved type of traveler support which will permit the traveler to be quickly and easily threaded. Another object of my invention is to provide a suitable support for a traveler which permits threading to be accomplished with sufficient speed to use the traveler type of spinning machine for yarn as it issues from the cabinets where it is made; Still another object of my invention is to provide a simple and inexpensive construction which can be easily kept in working order, and-other objects will appear from the following specification, the novel features being particularly pointed out in the claims at the end thereof.

It is now common practice to use a cap spinning device for direct winding of yarn as it issues from cabinets in which it is made. Cap spinners have certain disadvantages due to their cost and weight, and are in addition expensive.

In accordance with my invention, I have improved the threading of the traveler type of ring spinner sothat it is entirely suitable for use with yarn issuing from a cabinet as well as for retwisting the yarn.

Coming now to the drawing wherein like reference characters denote like parts throughout:

Fig. l is a plan view of a. traveler type of ring spinner constructed in accordance with and embodying a preferred form of my invention.

Fig. 2 is a side elevation partially in section showing the ring spinner of Fig. 1 and indicating its relation with a bobbin on which the yarn is to be wound.

Fig. 3 is a plan view of a ring guide constructed in accordance with my invention.

Fig. 4' is a section taken on line 4--4 of Fig. 3.

Fig. 5 is an enlarged fragmentary section taken on line 55 of Fig. 3 and showing a traveler v supported by the ring.

erse bar 6 in any suitable Way, as by bolts I, so

that the ring 4 may be moved as a unit with the ring holder I as the traverse bar is ,moved.

The ring 4 is provided with an outwardly extending flange 8, best shown in Fig. 4, this flange continuing around the major portion of the ring, but leaving an unflanged portion 9 approximately equal in length to the distance between the ends 5 of the ring holder arms 2. Over the area 8, as shown in Fig. 4, the cross-section of the ring 4 is quite thin. This permits a traveler II] to be readily threaded, as will be hereinafter more fully described. The flange 8 of the ring 4 is adapted to fit snugly in the groove 3, in the arms 2, and in the base I, preferably so that the flange 8 fits flush with the upper surface II of the ring holder.

In order to hold the ring firmly in position, I

prefer toprovide one or more headed screws I2 which are threaded tothe arms 2 so that the head of these screws may hold the flange 8 tightly in the groove 3.

The traveler III, as shown in Fig. 5, may be conveniently formed of a piece of round rod stock bent over at its end I3 in such a manner that the traveler will be held on the ring 4. The bent ends I3 of the traveler II) are spaced from the body portion of the traveler a distance somewhat greater than the thickness T of the ring 4 so that the traveler can slide quite freely upon the ring and be guided by it. The spacing is .such that by pressing in upon the ring II), the bent end l3 will be spaced from the. ring a distance sufficient to thread the silk S quickly beneath the hook like end I3 of the traveler. When the traveler starts to move rapidly around the ring, the yarn will assume the position shown in Fig. 2, ballooning about bobbin I5 as it is wound thereon. Bobbin I5 may be of the usual type. including a lower flange I6 and an upper flange II. The bobbin may have a handle I8 to facilitate placing it upon the spindle I 9 and the bobbin may be driven in the usual manner through a connection with a pulley 20 about which a driving belt passes.

The operation of the traveler type ring spinning machine constructed in accordance with my invention is very simple. The yarn may be readily started to wind upon the bobbin by drawing out a loop of thread in the usual manner, passing the strand beneath the bent end I3 of a traveler III which has been positioned over the area 9 of the ring guide, and thence bringing the loop through the inside of the ring 4 and touching it against the bottom flange I6 of the rotating bobbin. The thread is immediately From the foregoing description it will .be seen that because of the construction of the ring guide and ring holder and because of the construction of the traveler itself, yarn can be very rapidly threaded beneath the ring and attached to a take-up spindle.

While I have shown a preferred embodiment of my invention, it is obvious that various changes can be made without departing from it. I consider as included within the scope of my invention all such forms as may come within the terms of the appended claims.

What I claim is:

1. In a traveler type of ring spinning machine for artificial silk, the combination with a ring holder including a pair of curved arms, an armate seat included in the curved arms adapted to receive a flanged ring, the flange extending only partially around the ring whereby the ring may have a compact cross section over a portion thereof, and a traveler adapted to be guided by the ring and, when the traveler lies over the unfianged portion of the ring to be readily threaded with yarn.

2. In a traveler type of ring spinning machine for artificial silk, the combination with a ring holder including a base adapted to be mounted on a traverse bar, curved arms carried by the base separated at then outer ends, a ring adapted to be carried by the curved arms, the ring including an outwardly extending flange passing around the greater part of the ring but having an unflanged area,and a traveler in the form of a U-shapedmember'adapted to be guided by the ring in winding yarn on a bobbin, said traveler beingreadily accessible for threading when positioned on anunflanged portion of the ring between the ends of the curved ring supporting arms, wherebythe traveler may be readily threaded.

3. In a traveler type of ring spinning machine for artificial silk, the combination with a ring holder including a base adapted to be mounted on a traverse bar, curved grooved arms carried by the base separated at their outer ends, a ring adapted to be carried by the curved grooved arms, the ring including an outwardly extending aosayei traveler may be readily threaded 4.. In a traveler type of ring spinning machine for artificial silk, the combination with a ring holder including a base adapted to be mounted on a traverse bar, curved grooved arms carried by the base separated at their outer ends, a ring adapted to be carried by thev curved grooved arms, the ring including an outwardly extending flange of a size and shape to fit into thegrooved arms and passing around the greater. part of the ring but having an unflanged area, and means to hold the flanged ring in the grooved arms, and a traveler in the form of a U-shapedmember adapted to be guided by the ring in winding yarn on a bobbin, said traveler being readily accessible for threading when positioned on an unflanged portion of the ring between the ends of the curved ring supporting arms whereby the traveler may be readily threaded.

5. In a traveler type of ring spinning machine for artificial silk. the combination with a ring holder including a base adapted to be mounted on a traverse bar, supporting arms carried by the base and including an arcuate groove, the ends of the arms being spaced apart, a ring including a flange extending only partially around the outside thereof adapted to fit snugly into the grooves of the arms leaving an unflanged ring portion of narrow cross section extending between the spaced arms, headed screws engaging portions of the flanged ring to hold it in a predetermined position on the ring holder, and a traveler mounted on the ring and including a bent rod having ends embracing edges of the ring and loosely holding the traveler on the ring, the play between the traveler and ring being such that yarn may be readily entered between the traveler and ring when the former is positioned on an unfianged part of the ring.
